DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The utility model relates to a jet flushing device, which comprises a connecting seat 100 and a sealing component.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the connection seat 100 can be set to a cylindrical structure, or it can be set to other shapes such as a rectangular box. In this embodiment, the connection seat 100 is cylindrical, and the internal hollow of the connection seat 100 defines a water diversion chamber 110. The water diversion chamber 110 is opened at both ends and the side wall is opened. The upper end opening of the water diversion chamber 110 is a first water inlet 111, the side wall opening of the connection seat 100 is a first water outlet 112, and the bottom opening is a second water outlet 113. The first water inlet 111, the first water outlet 112 and the second water outlet 113 are distributed on the connection seat 100 from top to bottom. In addition to the above-mentioned positions, the positions of the first water inlet 111, the first water outlet 112 and the second water outlet 113 on the connection seat 100 can also be evenly distributed on the side wall of the connection seat 100, but are not limited to this. The sealing component is screwed on the outer wall of the connection seat 100, and the two can be connected by threads. The sealing assembly is located between the first water outlet 112 and the second water outlet 113 .

[0032] In this embodiment, Figure 6As shown, the jet flushing device is applied to a toilet. The toilet also includes a water tank portion 500 and a seat portion 600. The water tank portion 500 and the seat portion 600 can be a one-piece design, that is, the water tank portion 500 and the seat portion 600 are integrally formed. The upper part of the connection seat 100 of the jet flushing device is connected to the water tank portion 500. It can be that the upper end of the connection seat 100 is installed at the bottom of the water tank portion 500, and the first water inlet 111 is connected to the inside of the water tank portion 500. The seat portion 600 is a ceramic body, and the seat portion 600 is provided with a brush ring water channel 610 and a bottom nozzle 620. The brush ring water channel 610 is located at the upper part of the seat portion 600, and the brush ring water channel 610 surrounds the toilet cavity 630 of the seat portion 600 and is provided with a plurality of water holes. An installation port 611 is opened on the rear side of the seat portion 600, and the installation port 611 is connected to the brush ring water channel 610. The connecting seat 100 is passed through the installation opening 611 of the brush ring water channel. The first water outlet 112 is aligned with the brush ring water channel 610 and is connected to each other. The second water outlet 113 passes downward through the installation opening 611 and is connected to the bottom nozzle 620. The second water outlet 113 and the bottom nozzle 620 can be connected by a hose. The sealing component is located at the lower side of the brush ring water channel 610, and then the sealing component is rotated, and the upper part of the connecting seat 100 overlaps the upper side of the installation opening 611, so that the sealing component seals the connection between the connecting seat 100 and the lower side of the brush ring water channel 610 upward, that is, the lower end of the installation opening 611 and the connecting seat 100 are sealed. The position of the sealing component on the connecting seat 100 can be adjusted, and the connection position can be quickly sealed, which is very convenient to install and use. The sealing assembly 100 can prevent water discharged from the first water outlet 112 to the brush ring water channel 610 from flowing to the second water outlet 113 through the installation port 611, so that the two water channels do not affect each other, thereby ensuring the flushing effect of the brush ring water channel 610 and the bottom nozzle 620.

[0033] In some specific embodiments of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the sealing assembly includes a triangular washer 420, an anti-skid washer 430 and an adjusting nut 440 which are sequentially sleeved on the connecting seat 100 from top to bottom. The connecting seat 100 and the adjusting nut 440 are connected by threads. The supporting washer 410 can be a foam washer, and the anti-skid washer 430 can be a flat washer. Figure 6As shown, the connecting seat 100 is penetrated in the brush ring water channel 610. By rotating the adjusting nut 440, the triangular washer 420 is pushed upward, thereby sealing the lower side of the installation port 611 of the brush ring water channel 610. Furthermore, a boss 140 is provided on the peripheral wall of the connecting seat 100 located above the first water outlet 112. The boss 140 can be arranged around the first water inlet 111. A support washer 410 is also sleeved on the connecting seat 100. During installation, the connecting seat 100 penetrates the installation port 611 of the brush ring water channel 610 downward, and the boss 140 and the support washer 410 are both located on the upper side of the installation port 611. The support washer 410 can abut against the lower side of the boss 140, and the boss 140 presses the support washer 410 downward, and cooperates with the sealing assembly to clamp and seal the upper and lower sides of the installation port 611.

[0034] In this embodiment, the second water outlet 113 is connected with a water spray pipe 200. The water spray pipe 200 is installed on the lower side of the connecting seat 100. The specific structure of the water spray pipe 200 is not limited. It can be that the water spray pipe 200 has a first water inlet end 210 and a first water outlet end 220, and the first water inlet end 210 and the first water outlet end 220 are distributed up and down. It can be that the water spray pipe 200 is installed obliquely, and the first water inlet end 210 is connected to the second water outlet 113. The first water inlet end 210 and the second water outlet 113 can be connected by plugging, and then further locked by using components such as clamps. Among them, the opening of the first water inlet end 210 is larger than the opening of the first water outlet 112, that is, the water flow cross-sectional area of ​​the first water inlet end 210 is larger than the water flow cross-sectional area of ​​the first water outlet end 220, and the water flow rate of the first water inlet end 210 per unit time is greater than the water flow rate of the first water outlet end 220. A large amount of external water enters the water diversion chamber 110 through the first water inlet 111, and the water flows from top to bottom along the water diversion chamber 110. A part of the water flows out of the water diversion chamber 110 through the first water outlet 112, and the remaining water is transported to the water spray pipe 200 through the second water outlet 113. The amount of water entering the water spray pipe 200 is constant, and the water flows downward along the water spray pipe 200. The gravitational potential energy of the water is converted into kinetic energy. In addition, since the water flow cross-sectional area of ​​the first water inlet end 210 is larger than the water flow cross-sectional area of ​​the first water outlet end 220, the instantaneous speed of the water increases when passing through the first water outlet end 220, which effectively enhances the flushing force of the water sprayed from the first water outlet end 220. The jet flushing device can be applied to various water-using equipment. Through the cooperation of the connecting seat 100 and the water spray pipe 200, the water is automatically diverted at the connecting seat 100, and sprayed out through the water spray pipe 200 at an increased speed to flush the external components. The water spray pipe 200 is inclined toward the bottom nozzle 620. The first water outlet 220 is connected to the bottom nozzle 620, and the two can be connected by plugging or the like, and then further fixed by fasteners such as clamps. A valve can be provided at the connection between the water tank portion 500 and the first water inlet 111, and the valve can be an electrically controlled valve or a manually controlled valve. After the water tank portion 500 stores water, when the toilet chamber 630 needs to be cleaned, the valve is opened, and the water in the water tank portion 500 is flushed into the water diversion chamber 110 through the first water inlet 111 according to its own gravity. A portion of the water is diverted to the first water outlet 112 and enters the brush ring waterway 610, and the water flows along the brush ring waterway 610 and flows from the water hole into the toilet chamber 630, and the side wall of the toilet chamber 630 is cleaned. The remaining water flows along the second water outlet 113, the first water inlet end 210, the water spray pipe 200 and the first water outlet end 220. After being sprayed out from the first water outlet end 220, the water flushes the bottom nozzle 620. The bottom nozzle 620 is connected to the sewage pipe. The dirt in the bottom nozzle 620 is discharged under the flushing effect and the siphon effect of the sewage pipe.Among them, the greater the slope of the water spray pipe 200, the greater the impact of gravitational potential energy, and the more powerful the flushing; the longer the length of the water spray pipe 200, the longer the distance the water flows. Under the same height difference, the potential energy of the water flow will become smaller due to the excessive length. According to this principle, water spray pipes 200 of different lengths, slopes, and water-passing cross-sectional areas are selected to be used in the toilet to ensure the flushing effect. In the case of a toilet with a complex and limited ceramic shape structure, the jet pipe replaces part of the ceramic waterway of the toilet to reduce the problem of poor flushing performance of the flushing waterway due to the limitation of the ceramic shape. The jet flushing device can effectively increase the intensity of the water spray flow to the bottom nozzle 620, achieving a good flushing effect, with a simple overall structure, low structural cost, and easy installation and use.

[0035] A water cut-off member 300 is installed on the connection seat 100, and the water cut-off member 300 is used to control the water outlet area of ​​the first water outlet 112. The water cut-off member 300 can be in various forms. For example, the water cut-off member 300 is set as a plate-like structure, and a mounting groove can be set on the connection seat 100. The water cut-off member 300 is slidably connected to the mounting groove, and the water cut-off member 300 can partially cover the first water outlet 112. When the water cut-off member 300 slides along the mounting groove, the covering range of the first water outlet 112 by the water cut-off member 300 will change, and water can be transported from the position of the first water outlet 112 that is not covered by the water cut-off member 300 to the brush circle waterway 610. That is, by moving the water cut-off member 300, the water outlet area of ​​the first water outlet 112 is changed, and then the water output of the first water outlet 112 is changed. According to the water storage capacity of the water tank 500, the water outlet area of ​​the first water outlet 112 is adjusted by the water cut-off member 300 to avoid insufficient water supply to the bottom nozzle 620 due to excessive water supply to the brush ring water path 610. In this way, the water flow to the bottom nozzle 620 is optimized. The water cut-off member 300 is used to adjust the displacement ratio of the first water outlet 112 and the second water outlet 113, so as to adapt to different toilets, improve the versatility of the jet flushing device, and effectively ensure the flushing effect of the toilet.

[0036] In this embodiment, Figure 3 , Figure 4 and Figure 5As shown, the water cut-off member 300 is annularly sleeved and attached to the outer wall of the connecting seat 100. The connecting seat 100 is cylindrical, and the water cut-off member 300 is correspondingly set to be annular. The water cut-off member 300 can move up and down along the connecting seat 100. A plurality of first water outlets 112 are provided on the side wall of the connecting seat 100. For example, four first water outlets 112 are provided on the side wall of the connecting seat 100 along the circumferential direction. When the water cut-off member 300 moves on the connecting seat 100, it can simultaneously partially cover each first water outlet 112 and synchronously control the water outlet area of ​​each first water outlet 112. The number and position of each first water outlet 112 are not limited, and one, two or more first water outlets 112 may also be provided on the connecting seat 100. Multiple first water outlets 112 may also be distributed up and down on the connecting seat 100, and the number of first water outlets 112 opened is controlled by the up and down movement of the water cut-off member 300. After adjusting the position of the water cut-off member 300, the water cut-off member 300 can be fixed at the current position by means of a latch or the like. Figure 4 and Figure 5 As shown, a plurality of latching positions 120 are provided on the connection seat 100, and each latching position 120 is sequentially distributed along the moving direction of the water cut-off member 300, that is, each latching position 120 is sequentially distributed up and down on the connection seat 100. The latching position 120 can be protruded in the form of a rib on the outer wall of the connection, or can be arranged in the form of a groove. An elastic hook 310 is provided on the water cut-off member 300. After the water cut-off member 300 is sleeved on the connection seat 100, the elastic hook 310 can be engaged with the latching position 120 corresponding to the current position, thereby fixing the water cut-off member 300 at the current position. Among them, in order to improve the positioning stability of the water cut-off member 300 on the connection seat 100, multiple groups of latching positions 120 can be provided on the circumferential outer wall of the connection seat 100, and the elastic hook 310 of corresponding positions and numbers can be provided on the water cut-off member 300.

[0037] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the connection seat 100 is also provided with a water replenishment channel 130, which extends into the water diversion chamber 110 and communicates with the water spray pipe 200. In actual use, the water replenishment channel 130 can be connected to a water pipe to communicate with the water tank part 500. An electric control valve is set on the water pipe to control the opening and closing. Whenever the bottom nozzle 620 is flushed, the valve member controlling the communication position between the water tank part 500 and the first water inlet 111 is closed, the electric control valve is opened, and the water in the water tank part 500 is transported to the water replenishment channel 130 through the water pipe. The water flows into the water spray pipe 200 along the water diversion chamber 110 and then discharges into the bottom nozzle 620 for water sealing. Further, the water replenishment channel 130 is provided with a second water inlet end 131 and a second water outlet end 132. The second water inlet end 131 extends to the outside of the water diversion chamber 110. It can be that the second water inlet end 131 extends horizontally to the outside of the water diversion chamber 110. The second water outlet 132 extends into the water diversion chamber 110. The water replenishment channel 130 extends along the inner wall of the water diversion chamber 110 toward the second water outlet 113. When the water flows along the water replenishment channel 130 and is sprayed out from the second water outlet 132, the water flows along the inner wall of the water diversion chamber 110 toward the water spray pipe 200, thereby preventing the water from splashing around and forming a dripping noise when it flows into the water spray pipe 200, thereby realizing silent water replenishment.

[0038] In some specific embodiments of the present invention, the water spray pipe 200 is arranged at an angle, so that the gravitational potential energy of water can be converted into dynamic potential energy. The water spray pipe 200 extends from the first water inlet end 210 to the first water outlet end 220 in a gradually narrowing shape, ensuring that water has sufficient impact force when spraying from the first water outlet end 220. Among them, the water spray pipe 200 is made of rubber tube material, which has a certain elastic deformation ability and can meet the difference in installation size when installed on the seat body 600.
